Using the Collection
We actively encourage both UA and external researchers to utilize the LTRR's world-class repository of tree-ring specimens.
Specimens at the LTRR presently fall into two categories: active research collections (administered by the project principal investigator - PI); and archived collections (administered by the Curator of Collections).
The first step in requesting a loan is to identify the specimens you need. The LTRR does not yet have a publicly accessible search portal so prior to most loan requests you will need to submit a specimen and records search request. Please email the curator with as much detail as you can. Once you have the list of required specimens the procedure is as follows:
Loan Procedure
-
The applicant downloads and completes the loan request form and sends either to the Curator (for archived collections) or to the Curator and the PI (for active research collections).
-
The proposal will be reviewed with potential exchange to clarify the request. There will be additional scrutiny on requests including destructive analysis.
-
The applicant will be notified and sent an invoice outlining the costs of preparing the loan including sub-sampling, cataloging any uncataloged specimens, and shipping.
-
On receipt of payment the specimens will be prepared and dispatched.
-
The applicant will perform great science!
-
The applicant will return specimens within the agreed time frame (normally 6 months unless agreed otherwise).
-
The applicant will acknowledge the LTRR in all publications resulting from the use of the specimens. The applicant will forward copies of all these publications to the LTRR Curator.
